MACHINE FOR IVIAKI NG WIRE HEDDL'ES.

SPECIFICATION forming part of Letters Patent No. 235,602, dated December 14, 1880.

Application filed September 21, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES H. W'ILLIMIS, of Utica, in the county of Oneida and State of New York, have invented a new and valuable Improvement in Machines for Making Wire Heddles; and l do hereby declare that the following `is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and gures of reference marked thereon.

Figure 1 ofthe drawings is arepresentation of a longitudinal sectional view illustrating this invention. Fig. 2 is a plan view showing the cylinder and stock-heads in horizontal section 5 and Fig. 3 is a view, in perspective, of a portion of the cam g g.

My invention relates to certain improvements in machines for making wire heddles; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth.

The invention is designed as an improvement upon the patent granted July 14, 1868, No. 79,905, and its Reissue No. 3,724.; and the improvement consists in the devices which serve to bring the twisting-cylinders to their nearest approximate position immediately beally draw them apart or back away from the eye-former during the operation of finishing the twisting of the wires.

The cam g g tapering from the point ci' contact with the bars h h toward the rear, to accomplish thelobjects above stated, is the essential feature of the invention, and this, in connection with the mechanism necessary to make it operative, is all that is claimed as new herein.

The letters a c indicate the usual revolving hollow cylinders placed on each side of the pinchers e, which formthe warp-eye of the heddle. b b are head-stocks that support these cylinders, and in which they turn at the required times, their revolution being had ;by means of gear-wheels d d, driven by intermediate mechanism (not shown) from the main shaft j'. Each cylinder has, as nsual, two pairs of jaws, c c, one pair at each end, for the purpose of seizing and holding the wires that form theheddle during the operation of twisting the strands to form the eye, the wire being grasped for this purpose by the eye-forming pinchers e. Said jaws are arranged to werk in slots made in the cylinders lengthwise thereof, and are pivoted in said slots, as is shown in the drawings. rlhese jaws are opened and closed by the movement on the cylinders of the sliding collars n n, said collars being made with inclination and pins, which operate upon the tail ends of the jaws, as i-s clearly represented in the drawings. The sliding collars herein referred to are not claimed, nor are the jaws c, which they operate, as these devices are in common use in wire-heddle machines.

' The sliding collars n a are moved to and fro by a cam, g g, formed on a portion cf the disk .,r, placed on the shaftf, the cam being so formed as to move the collars on the cylinders to close the jaws, and hold them closed on the heddle-wires while the twist is being given to the heddle, the cam being so timed as to rer lease the cylinders and open the jaws assoon as the twist has been completed. Theforward end, e, `of the cam g g imparts motion to the collars n fn, and to the head-stocks in which the cylinders are seated, by means of sliding bars h h and sliding rods i i', being provided with forks j j', which enter grooves made around the collars, and impart to the latter the motion of the rods in the ordinary manner.

Each of the bars It it is provided with an i Preparatory to the revolution otl the cylinders, and before the twisting operation thereof has commenced, the distance between the cylinders or their jaws and thepinchers e is shortened, so that said cylinders are brought to their nearest approximate position and their jaws closed on the'wires, and then, during the twisting operation, this distance is lengthened for the more perfect twisting of the wires, compacting and setting the same nearest the IOO inner portion of the warp-eye by means ofthe following construction, which forms the main feature of the present invention.

rIhe cam g g, which is usually in two parts, each independent of the other, is formed by pivoting the forward or deeper ends of the arc-shaped pieces g g to an arc-shaped rib, q, projecting from the periphery of the disk r, said rib forming the foundation of the cam or cams. The rear or narrower ends ofthe pieces g g are slotted, as at p, to receive screws, whereby they are secured to the foundationrib q in any desired position of eccentricity to the center ofthe shaft j'. The forward ends, z, of the cams are deeper than their rear ends, so that the cams taper to the rear, as shown in the drawings, and the forward ends, z, of said cams are made sufficiently deep to not only close the jaws by the movement of the collars n n, but also, through the engagement of said collars with the shoulders s s ofthe cylinders a. a', move the latter and their head-stocks b b toward each other to their nearest approximate position. lhehead-stocks b b are movable in grooved beds, being held therein by screws u, which go through slots c in the bottom of said beds.

When the cylinders andtheir head-stocks have been moved to their nearest approximate position, as stated, then the twisting operation is commenced by the rotation of the cylinders, and at the same time the bearing-ends of the rods h h', havingcome into engagement with the inclined portions y y of the gradually-narrowing cams g g, said l'rods are allowed to recede from each other, and the head-stocks b b and their cylinders are pressed apart or away from the eye-forming pinchers e duringthe twisting operation, but not far enough apart to'release Ithe cylinder-jaws, the portions y y of the cams keeping these closed until the ends of the rods h It are passed by the ends of said cams and become disengaged therefrom.

The operation of moving the Ihead-stocks l) b back or away from the eye-formin g pinchers is performed by the spring l, which is arranged on a rod between the movable head-stocks in rsuch a manner that it becomes compressed by their movement toward eachother, and tends constantly to press them apart.

The operation of moving the collars n n back on their cylinders is performed by the springs l m, which carry the ends of the bars 7th to the disk o' when the cams gg have passed by them, and the cylinder-jaws are thereby released, so that they open and release the heddle.

The wires that form the heddle are drawn into the machine through the spindle or cylnder a2, at the receiving end of the machine.

The warp-eye is formed by the pinchers c and the twisting-cylinders, and as thejaws of the latter are moved to their nearest approximate position, and the jaws then closed upon the wires and then recede forcibly from the eye-forming pinchers during the twisting operation, it is apparent that the twist is compacted and the wires set in the twisted portion, especially in the parts nearest the inner portion of the warp-eye, so that the latter, when completed, will present a iirzn unyielding surface to the action of the warp in those portions which are subject to the greatest strain when the heddle is in use on the loom.

The setting effect on the wires produces a hard twist, which retains its form and is not liable to spring, so as to leave crevices at the ends of the eye, which would catch the warp and fray or wear the same.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In a machine for making wire heddles, the combination, with the movable headstocks, cylinders, and jaws, and the eye-forming pinchers e, of the bars h h, rods i t, spring l, and the cam g y, having its point of greatest eccentricity at its forward end, z, and gradually approaching the shaft at y, whereby the cylinder-jaws are moved to their nearest approximate position and closed before the twisting operation commences, and recede during said operation, cutting the twist at the ends of the warp-eye, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
